Application filed September 23, 1on9. Serial so. sienna To all whom; itmay com-em;

Be it known that I, ALFRED G. F. Kn- ROWSKI, a citizen of the UnitedStates, residing in New York city, borough of Bronx, in' the county ofNew York and State of New York, have invented certain new andType-VVriting Machines, of which the following is a specifica- Hon. 1 v

- This invention relates to improvements in typewriting machines, andthe object is to enable an operatorto conceal the typewritten sheet in.the maclune from the gaze of [urn authorized persons.

A screen is provided so mounted as to en able'th'e operator, to throw itinto effective position, or to throwit out of the way when insertingorremoving a sheet, or correcting errors. 1

Thep laten frame is provided with an opaque screen adapted, when in oneposition, to overhang the platen and the sheet to prevent it from beingscanned. This screen is capable of being swung upward and tiltedbackward out of the way, to permit access to the platen. Preferably,supporting arms are arranged to swing with the screen relative to theplaten frame to more room.

In the accompanying drawings, Figure 1 is a perspective View showing oneform of my invention applied to-the platen of an Underwood type of frontstrike Writing machine, showing the screen in operative position. Fig. 2is a fragmentary front view of F ig. 1. Fig. 3 is a cross-sectional Viewshowing the screen in concealing position, dotted lines showing thepositions of the screen when tipped backward to permit the correction oferrors. Fig. 4 is a cross-sectional vlew showing the screenswungbackward out of the way.

A platen A has an axle l journaled in a platen frame 2, which alsocarries the usual paper shelf 8. The paper 15, is usually fed into themachine between and platen, and is held in place by the fingers andguides 5. To supports 6 is pivotally secured a concealing screen 7. Thisscreen projects forwardly and downwardly to a point just above theprinting pointand in front of the platen, overhanging the latter,asshown in Figs. 1 and 8, so that the writing is concealed. The operatorcan continue. writing, the paper being fed upwardly give the operatorthe paper shelf form a passageway 17 The screen 7 is partly supported byrests 8 on the supports 6 forward of the pivotal supports 16 of thescreen 7. i

' Preferably, I pivot the supportsfi to the platen frame, as at 11, topermitthein to be thrown backward, as shown in dotted hues in Fig. 3,together with the screen 7, to pen mit the operator tomake'erasures,-botlr the screen and" the supports moving about thepivots 11, and the forward or lower edge of the screen being raisedsuiiiciently to permit play of the operatorshands between the same andthe platen.

In operation, the screen and its supports are first thrown back onthepivots l1 and 16, as shown in Fig. 4, wherein the screen forms anextension of the paper-shelf 53, the rearward extension 9 of the screenengaging the curl 10 of the paper-shelf. In thisposition, the screenforms an extension of the paper shelf andfacilitates the insertion ofThe operator supports forthe sheet into the machine.

then swings the screen and its wardly on the pivots 11' and 16 totheposition shown in full lines-in Fig. 3, with the screen concealingthe paper as it issuesin front of the platen and travels upward-andbackward through the passageway 17. If it:

is necessary to make correctirms, the screen and its supports are swungtogether on the lines .in Fig. 3. To remove the sheet, the screen andsupports are swung backward to the position shown in Fig. 4.-.

- If desired the supports may be rigidly secured to the platen frameinstead of being pivoted thereto.

The supports 6 have stops 12 and '13, and

The platen coperates' paper advances towardpivots 11 to. the positionshown in'dotted the supports may be connected by a brace 14;.

It will be observed that the supports and brace constitute a frame forsupporting the screen, and that the; shiftable screen is capable ofbeing swung from its concealing position, to partially or wholly uncoverthe platen and paper carried thereby.
